hemipenal sheds

brick1 May 09, 2008 03:26 PM

just wondering when these are seen? are they seen on all adult male sheds? are they seen as a male is ready to breed? or are they shed at different times to the normal sheds?

from everything i have read about the breeding from different peoples pages, i have never seem to find this info. Just seen a few pics that think mike and dave posted on KS a few months ago

cheers
dave

Not rock solid info, just my thoughts and observations....

The hemipenal shed (HS)is only found when adult males are excited by the smells of a female putting oot those "come and get me big boy" pheremones. Has nothing to do with the epidermal sheds both males and females go through. The HS is a great indicator of sexual activity, at least the male can sense a female in the vicinity going through the reproductive cycle. Note: may also be induced by the temperature cycling we put them through to get them to breed although I have heard reports of non-cooled males producing them.

Most noticable when left in a water bowl although I have identified many left in various locations within the enclosure. At least I believe that's what they were, when left on a dry surface, they will dry up and turn into a crusty smear.

and have you always found them for each of your breeder males? or is it a bit of hit a miss?

another thing was wondering about, for people like you dave, who has a big snake room, do you heat the whole room to a set temp? if so, how do you cool your snakes? and if its just by lowering the whole room temp, does this not affect you BCI and BRB neonates?

cos my snake room i think i would struggle to get under 22degrees celsius, the apartments here are just to well insulated!!! all the windows have double or triple glazing etc. But you cant open the windows here either, as the temp gets below minus 20 celsius in the winter, so a bit unsure what the plan will be there

Not alwasy found, sometimes found later stuck to the sid epof something, sometimes several form a single male... Yeah, hit and miss but alwasy a good sign when found.

I do not heat the room but with all the cages it stays pretty warm. And yeah, it is a bit of a problem getting the temps down for the BRB's while keepin the BCI warm enough. Yet another good reason for the second room. BRB breeders in one, BCIU breeders in the other, subadults wherever they fit!!

I do cool by turning down the individual t-stats, kinda does not work though to lower below the room ambient.

22 degrees Celsius would be adequate as a NTL (night time low)

That temp will cycle BRB well enough to reproduce.

With a DTH (day time high)of 27 to 28 degrees Celsius.

You could use a hot spot to create the DTH and remove it to create the night time low.

I for one believe cycling improves the outcome of breeding success but is not essential to get a viable outcome breeding BRB's and many other Boids as well.

Most people cycle Ratsnakes to get a viable outcome. I have got eggs from a female Texas ratsnake cooking right now, not one clutch but two. (female double clutched 9 eggs then 30 days later 14 eggs) Now this may not be a Boid but it is an example of how cycling may not always be necessary to get a viable outcome when it comes to breeding snakes.

Although I have only bred BRB's twice in the past and I did cycle them to at least 75 to 84 degrees to achieve it. It would be safe to say I hit 70 degrees on a few occasions and as high as 86 a few times as well. When hot spot hit 85 the female BRB got as far away from it as was possible still staying in the high 70's low 80's as a body temp.

I have never seen the stuff till this year.

same day...

Dave,
....I think they are just the snaky version of a wet dream. They do it fairly often during breeding season when they can smell females. When they leave it in a water bowl it retains the identifiable shape of the hemipenes. Most of the time they just leave the specimen on the cage floor or furniture and it is just a smear with no identifiable shape. Any kids reading this forum please do not tell your mom that I am posting about wet dreams.

haha a snake wet dream hey. Ok well once again was just something to add to my massive list of questions going around my head. Was just trying to work out if needed to see it, ie it was a sign that the male was ready to breed etc etc.
